. In my pending application above referred to means are disclosed for periodically closing andopening an electric circuit and for pre-detern1ining intervals during which the periodic closing and opening shall be ar- 'ested. In conjunction with means for performing those two functions, means are also disclosed for rendering the periodic closing and opening means operative during pre determineo inoperativev intervals, 1ncluding a manually operated shift lever by means of whichsuch adjustmentof parts is secured as to accomplish this thirdfunction. A plurality of indicating or number wheels periodically actuated are disclosed in the patent above referred to on improvements in time recordingregisters, these indicating wheels being changed periodically and consecutively. Infact, in practice they constitute a form of cyclorneter. Apparatus is also shown, manually operable, for idling certain of the 'indiati'ng wheels of the register while continuing the periodic consecutive change of others of the indicating wheels." v I v The present: invention, among other things, combines the apparatus disclosed in the above mentioned pending a plication with the apparatus constituting the subject matter oftheabove mentioned patent into one co-acting machine and prov des means whereby the manually operated shift lever, through cesareann11 the idling apparatus in the register, causesi it to be operative or inoperative. Besides oVerningthe operation of the idling mesia'nisrnin the register'the throwil bf the shift lever likewise provides fdifthgeiiifisertidir"in the line of printing type ofjt lie' register a character indicates il pbn Ithe .r'ecord'taken from the register'tliat the idling mechanism is in operative position.

In Fig. 2 of'the 'dr awings reference nu.- m ralt win rie l, t h r curedja franie-plate 21, the members 20 and 21, together with porting arms 22, repe t feny ei' b fi e e 's f pp ing, time controlledfelectric switch mechanism andfor su portin a clock movement indicated genera I ly by not illustrated in detail. The frame workfor the switch mechanism portioniof my invention. is indicated reference'numeral 23 and is adapt ed tofsuppo r't the various parts'of the mechanism 'in thein'proper positions.

Suitably mounted upon a horizontal pivot post 24: secured in the frame 23 are two pivoted blocks of insulating material 25 and 26 which-carry respectively electricity conducting switch arm's'27 and 28, bearing one tlie'female portion 31, the other the male portion 32, of an adjustable circular knife switehiip'on'their forward ends. The switch arms 27 and 28 extend rearwardly of the insulating blocks 25 and 26 and bear upon their rearward extremities a carbon makeand-brea lodevice "including two car bon blocks 29 and 30 which, by contacting with each other before the closing of the knife switch and by separating'from each other after the opening of the knife switch, to.protect theknife switch from arc ing. The specific construction of this switch is set forth in the previously mentioned pending application on time controlled switch mechanism for'electric Circuits, and for that reason 'is'not here inserted.

The switch arms 27 and 28 are preferably secured to the upper surfaces of the insulating blocks 25 and 26"and to their lower surfaces are secured two rider arms 33 and 34 of slightly different lengths and extending forwardly of the insulating blocks The rider arms 33 and 34 ride upon the peripher of a ratchet wheel 35 rotated directly by the clock A. The passing of the points of the ratchet wheel 35 moves the rider arms in such manner as to close and open the knife switch above described at the pas; sage beyond the ends of the rider arm's 23 and 24 of-each" point. In this manner the knife switch is normally actuated to close and open an electric circuit periodically. 'Details of this periodic closing and opening mechanism are set forth in the above mentioned pending application on time controlled switch mechanism "for electric circuits andfor that reason are not giverfhere.

A swinging detent lever36, weighted at one of its ends as at 37, is suitably sup-' ported by the'frame work 23'and' has a normal tendency during the upper position of the rider arm 34 to catch that'rider arm and withholdit 'from 'its normal periodic switch closing and opening action. A tWenty-four hour cam wheel 38, suitably journaled on the frame work 23 and provided with a plurality of adjustable cams about its periphery is rotated by the clock A, and a rider post 39 rigidly" secured to one end of the swinging-detent 36 mounts and rides upon"'1the ""ca'ms o'f the-wheel to withhold the detent from contact With'tlie rider arm 34. Normally the'ri'de'r post :59 rides upon adjustable cams i() ,'41,42', and 43, which cams lie close to' the planeof the cam wheel 'and preferably contactwith it on one side or'the other-J Another'adjustable cam 44 rotates with the twenty-four hour cam wheel '38=bu t' is space d somewhat therefrom in order'that it shall normally clear the free end ofthe rider post 39;" By adjustment of the cams 40, 41, 42, and 43 upon the wheel 38 various portions of the circumference of the wheel 38 may be left without cam surfaces, and during the passage of these uncammed portions of the circumference of the wheel 38 past the rider post- 39, the rider post, having nothing to support it, falls, allowing the swingingde tent 36 to catch" the rider arm 34 and thus arrest the switch arm 28 from its normal action of periodically closing and opening an electric circuit. In this manner are predetermined eertain portions of the during which the normal closing and opening of an electric circuit by means of the switch is arrested, A Specific description of the pre-determining arresting mechanism just described forms part of my pending application on time controlled switch mechanism for electric circuits previously mentioned and is, therefore, omitted here.

The swinging detent 36 is shiftable within the spaced cam 'It may be shifted, however, by means of its connection with a manually operable shift lever '45, handled for convenience as at 46 and provided with a bifurcated,off-s'et inner end 47, to a position wherein it will mount and ride upon the s'paced'ca'r'n :t4the bifurcated end 47 being disposed about the detent lever. 36 to actuate 'it,ia.iidfthe"s'hift lever 45 being pivoted intermediate its ends as at 43. Normally the spa'ced cam 44 clears the'outer end of the rider post m'aking the knife switch inoperative during the passage by the rider pos'tof the uncammed portion of the cam wheel 38 ,lyingflbetwe'en the earns 43 and 40;

in'iother'words, the period during which thatuncamined portion of the wheel 38 is passing the rider post 39 constitutes one of thefpre-determined inoperative intervals of tlieI sivitch mechanism. By movement of the shift lever 45, however, and consequent shifting forward of the rider post 39, the post'g'may be madefduring this pre-determined inoperative interval, to mount and ride upon the spaced cam 44:, thus rendering operative'the periodic closing and opening function ofQthe switch during pre-determined inoperative intervals. A more minute description of the means for making the periodic closing and opening switch operative during pie-determined inoperative intervals is'set forth in the above mentioned pending application on time controlled switch mechanism for electric circuits.

In the present invention a block of insuliiting material 49 (see Figs. 9 to 12 inclusive) issecured to the frame work 23 and carries upon one of its sides and adjacent the top two binding posts 50 and 51. The block 49 also carries upon its opposite side and adjacent the bottom a pair of binding posts 52 and 53. Any means for energizing an electric circuit with a direct current of elect ricity,'such as an electric battery, is indicated'at B in Fig. 9, and the terminals 54L and 55 of the battery are connected respec tively tothe binding posts 50 and 51 of the block 49. The block 49 is attached to the frame work at one of its ends and upon the opposite end it carries four switch point arms 56, 57 58, and 59, which carry respectively the adjustable switch points 60, 61, 62, and 63, these switch points being preferably in the form of screws threaded into the switch point arms. The binding post 52 is electrically connected to the switch arm27 by means of a preferably flexible. conductor 61, and similarly, the binding post 53 is electrically connected to the switch arm 28 by means of another flexible conductor 65. An electrical conductor 66 connects the binding posts 50 and 52, the binding post 52 extending through the block 49 into threaded engagement with the lower end of the conductor 66. The switch point arms 57 and 59 are somewhat longer than the switch point arms 56 and 58, and the switch points 60, 61, 62, and 63 are preferably'so positioned as to lie in the same horizontal plane and be disposed with their contact points all ljietween the vertical planes of" the respective switch point arms, that is, the points 60 and 61 project toward the points 62 and 63, and the points 62 and 63 project; toward the points 60 and 61. The binding post 51 secures to the block 49 both the long upper switch point arm 57 and the short upper switch point arm 58, likewisejoining them electrically, and similarly, the binding post 53 secures to the block 49 both the long lower switch point arm 59"and the -short lower switch point arm 56, as welljas joini'ng these two arms electrically. Upon'aj pin 6'7hori zontally secured at one end to the frame 23 is pivoted an insulating block 68 which carries adjacent one of its ends two spaced'reversing arms 69 and 70, which extend upwardlyl parallel with each other; andare adapted to contact simultaneously either with the pair of switch points' 60 and 61 or the pair of switch points 62 and 63 according as they are pivotally. actuated?- The means for actuating the reversing arms cora prises a downwardly extending bar 7 1 upon the end of the block 68 'oppo'site theehd'to which the reversing armsaresecured,"a c n: neeting link 72 upon the lower end of the bar 71, and an arm 7 3 formed upon the shift lever 45 and to which'tlie other end of the connecting link 72 is joined. In Figs." 12 and 13 are shown two positions of the re- :ersing arms 69 and 7O, and the reversing mechanism just described, one of the positions being shown in full lines and the other in dotted lines. By this construction the shifting of the shift lever 45, besides adjusting the rider post 39 into such position that it will make the periodic closing and opening switch mechanism operative during pre determined inoperative intervals, will also more the reversing arms 69 and 70 from contact respectively with the switch points 60 and 61 across to contact respectively with the.

plurality of indicating wheels 76, 77,78, and 79 are respectively mounted upon and have rotation with concentricshafts 80, 81, 82, and 83, the shafts being rotated by ratchet wheels 84, 85, 86, and .87 respectively, The ratchet wheels 84:, 85, and 8,6 are provided respectively with side disks 88, 89, and 90. These side disks are of different diameters and are each notchedat one point of the periphery for engagementwith'an' actuating pawl 91 which operates the ratchet wheels 84c, 85, 86, and 87 consecutively and consequently changes the indicating wheels 76, 77, 78, and79 consecutively, the action of this mechanism beingvirtually that of the ordi For the purpose of clean.

fromf falling .sufiiciently to engage the ratchet wheel until the notched portion of the side disk 89 is presented to the pawl, at which time the pawl is a llowed to drop sufliciently toengage theratchet wheel" 86. The same action is true ofit-he side disk 90 uponthe ratchet wheel 86 with reference to the action of the pawl 91 upon the ratchet wheel. 87, the ratchetlwheel 87 not being ac.- tuated by the pawl until the notch of the side disk 90 is in engagement with the pawl 91. Thepawl 91.has a path of movement shown in Fig. 15 by full lines and dotted lines. It is actuated in this path of movement by means of an electro-magnet 92 electricallyconnected to the conductors 74- and 75, a plate 93 forming an armature for the magnet, and a lever 94 secured to the plate 93. A spring member 95 actuates the lever 94 to move the pawl 91 normally into the position shown in dotted lines in Fig. 15, while the electro-magnet 92 periodically moves the lever 94 to draw the pawl 91 into the position shown in full lines in Fig. 15. The above mentioned portionsof my time recording register. as well as its frame 96, being minutely described in the above mentioned patent a more specific description of them is here omitted.

In the present invention a collar 97 is disposed for oscillation about the shaft 80. At one of its ends this collar is provided with a cam 98 so placed that in one position of the collar the cam is operative to withhold the pawl 91 from dropping into the notch of the side disk 89 and engaging the ratchet wheels 86 or 87. Normally the cam 98 is in an inoperative position with respect to the pawl 9l-the operative position of the cam being shown in Figs. 14 and- 15 and the inoperative position thereof in 16 and 17., When the cam 98-is inoperative the pawl 91 is free under the actionof. the electro-magnet 92. to perform its ormal fang:

Secured in suitable position to the frame work-96 is a polarized magnet generally 'in dicated by C. The polarized magnet may be of any suitable type, theijone preferred and illustrated in the drawings..cqmpr sing a permanent magnet 103, the poles'of which are indicated at 104- and 1051- Aypk 106 is secured to the pole 104 and is upbent atone end as 107 for convenience 'in' attachin'g polarized magnet-C to the frame 96. To the yoke 106 are secured two soft iron cores 108. and 109, about which are disposed tespectivcly electric coils 110 and 111. These coils are electrically joined as at 112, and, the

conductor 75 is connected to the coil 1 1 O while the conductor 74 is connected to the coil 111. To the pole 105 of the permanent magnet 103 is secured a bearing113 in which is mounted a shaft 11% carrying a Soft iron armature 115 in such position that the side surface of the armature faces the pole of the permanent magnet, leaving a slight airgap between. Opposite the ends of the soft iron cores 108 and 109 the armature 115 is bent into contacting arms 116 and 117. The armature lever is rigidly secured to the soft iron armature 115 by any suitable means such as the cap screws 118. By this construction the movement of the armature 115 is communicated to the armature lever 102 and thence to the cam 98 and the indicating en, ev ve y he:

. H cent its cammed end with a power arml'gg character 99. In the present exemplification of my invention the polarized magnet C is shownconnected to the conductors 74c and "75 in parallel with the electro-magnet 92,

but such connection is not essential, for the same resultsmay be obtained if the electromagnet 92 and the polarized magnet Care connected to the conductors j 7 4,,and. 75 in series, theelectro-magnet 92 being operable to :perform its function-jregardle ss of the direction of How ofcurrent,in;.the;conductors =7+L and 75. The direction of flow of current in the conductors T4 and 75 governs theaction of the polarized magnet C and consequently the positioning of the' cam 98 and the indicating character 99. The direction .of .fiow;, ;of'.the current in. theconductors Z4 and 75,.isegoverned by. the positionqofuthe reversing arms 68- and 70, and the position which they occupy is ,in turn controlled .by. the location of the shift lever 45 at one end or-the other of .itspath of shift.

- ;In the use of my invention it is desirable at times to cause periodic closingandppening of the electric circuit-described during pre-determined inoperative intervals, and when such action of the apparatus; is desirable itis also necessaryto interposeinthe indicating or printing line. of;- -th e iindicating wheels some character -which .;shal1 show clearly that the electric circuit isbeing :pe riodically closed and opened during ;a predetermined inoperative; .interval. practice during the normal working hours of the day the electric circuit is periodically closed and opened. The? pie-determined inoperative intervals represent normally the noon:='hour-or.the night space between the close of normal working hours in theevening and the commencement .of normal working hours the next morning. When men are to be employed in overtime work, theshift lever 45 and the reversing arms 69 and 70 are thrown into the position shown in full lines in Figs. 12 and 13, which simultaneously places the rider post 39 in position to mount and ride upon the spaced cam Being upon the spaced cam -14 during a pre-determined inoperative interval, the rider post will withhold the detent 36 from contact with the rider arm 34 and allow the switch members 32- and 31 to meet and separate periodicallyr During the, normal working hours the'a'eversing arms 69 and 70 are in contact respectively with the contact points 60 and 61, which cause the electric current to pass through the conductors 74 and 75 in such a direction that the contact member 117 of the polarized magnet C will 'bedrawn to engagement with the soft iron core 109, thus throwing the cam 98 and indicating character 99 into the position illustrated in Figs. 16 and 17; namely, into their inoperative positions. lVhen, how

ever, by the shifting of the shift lever 45 into the position shown in full lines in Fig. 13 the reversing arms 69 and 70 are thrown across into contact respectively with the contact points 62 and 63, the direction of How of current through the conductors 74 audit-5 is reversed from that traversed during, normal working hours, causing the contact memberllfi to be attracted to the core and throwing the ca m 98 and the indicating character some; the operative positionsshownFigs. l and 15. Y

'hen in their operative positions the ind cating character 99 assumes a place in the indicating or printing line of-the indicating -w-heels 76, 8, and 79 while simultane ,ously the paw l; ;9l, contacting with the cam 98, isriallowed toactuate only the ratchet wheels; 18% and and their respective indicating, wheels m and, 77, leaving idle the ratchetwheelsfifi and 87 andtheir. respective indicating wheels 78 andv79. At the closeof the normal working hoursof the day a, definite number of hour periodsare indicabedby the-indicating Wheels76, 7 7 78, v

and .79;, whichnumber, under normal conditions, would remain in j indicating position in theregister until the beginning of normal working hours the following morning, .the periodic closing andopening of the electric circuit being normally; arrested during that -period. g g- But, when it. is desired to employ the apparatus in indicating overtime during the night, the amount oftime worked will-ordinarily. be somewhat less than the number of time units represented by one complete cycle of theindicating wheels 76 and? grit. being the practice inthe use of my present invention to actuate the indicating wheels once every tenth of an hour. Under this practicesomething less than one hundred of such. time periods would represent the ordinary amount ,of time consumed in overtime Workat night in a factory. For this. ,reason the spaced cain44 is constructed of such a length that it will cause the periodic closing and opening of the electric circuit during exactly one hundred periods. It is obvious then that if only the indicating wheels 76 and 77 are actuated during the period of overtime work and if the indicating wheels 78 and. 79 are idleduring that time, the number of hour periods indicated at the end of the overtime period .will be identical with. the number indicated at the beginning of that period.

. At the close of the normal working hours of the day. the periodic closing and opening of the electric circuit is automatically arrested by. the falling of the rider post 39 from the cam 40. \Vhen it is proposed to vwork overtime during the night the operator in charge moves the shift lever 45 into the position shownin full lines in Fig. 13. This shift of the lever causes a reversal in the direction of flow of current in the conductors 74 and 75, a throw of the armature 115 into the position shown in Fig. 15, and the placing in operative position of the cam 98 and the indicating character 99. Being in this operative position the cam 98 allows the pawl 91 to actuate only the indicating wheels 76 and 77 which, it is to be understood, are the units and tens wheels of the "set. In practice, and regardless of theshortness of the overtime period worked,- the rider post 39, is allowed to'rid'e upon the'cam 44 for the full length of the cam, which will cause one hundred changes of the indicating wheels and Ward leave them, when the rider post falls from the cam H, in the same position they-occupied at the close of the preceding normal working hours. Between the time when the rider post 39 falls from the cam 44 and the commencement of normal working hours the following morning the operator changes the shift lever 45 into the position shown in dotted linesinfl?"ig.'1 5, which reverses the direction offlow of current in the co'ruiluctors' 74 and and causes a shift of the cam 98 and indicating character 99 to their inoperative positions, as illustrated in Figs. 16 and 17; 'VVhen the men who work during the normal working hours of the day resume their work the-following morning after an overtime night period'h'as been worked, the cards which they print in the recording register will-show the same number at the beginning of the normal morning working hours that the'y'did at the close of the previous days' normal working hours. Consequently, if 'a workman began a piece of work at three'foclock in the afternoon of one day and the record printed by him upon his job card was, for example, 1212, and if he ceased work upon that job at the close of normal working hours that day, say six oc lock, and resumed work upon that job the following morning at the commencement of normal working hours, sayseven oclo'ck, and workedfor two hours on that same job in the morning, or until nine o'clock, the number printed by him at nine oclock upon his job card would be 1262, and the difference between this number and that which he printed when he began the job would show exactly the number of time units or tenth hour periods worked on that job regardless of whether or not the apparatus of this present invention has been employed to record overtime during the intervening night period. The job cards printed during the overtime period (the normally inoperatix e period of the periodic closing and opening switch) would each show, in addition to thecharacters normally printed upon a job card, the impression of the indicating character 99, which would illustrate clearly to the clerk handling the cards that the record made upon them was a record of overtime and not a record of normal working time.

The action of the polarized magnet C is such that it will remain stationary in the p dsition it assumes during the flow of the current in'a given direction until such time as the direction of flow of the current is reversed', when it'will assume its opposite po- 'sition. Thus the periodioen'ergizing of the eleet'ro-ma net 92 by the periodic closing f.

tion it, occupies during normal working hours, will remain in its reversed' position throughout the period of such shift of'the lever 45 for the reason that the flow of current during that period-is constant in the reve'rseFdirection. I
